8.1.2 Configuring With "User Assigned" Resources
As mentioned in the previous section, allowing the OS/2 Plug-and-Play system to
assign the hardware resources to the DSP-100 is ideal for OS/2 programs but can be a
problem if DOS and/or Windows applications will be accessing the serial ports. This
is because most DOS applications write directly to the communications hardware and
the Windows' Control Panel also wants to know the hardware configuration of the
serial ports. For this reason, the DSP-100 Client Driver allows the user to request
specific hardware settings using a series of command line arguments of the form
(port,address,irq)
port specifies the beginning COM port number
address specifies the base I/O address of the DSP-100 in hexadecimal and must
reside on an even 16-byte (10H) boundary.
irq specifies the interrupt level (IRQ) of the DSP-100 in decimal. irq must be
one of the following values: 3, 4, 5, 7, 9, 10, 11, 12, 14, or 15.
Each argument must be enclosed in parentheses and must be separated from other
arguments by a space on the command line. Within each argument, the parameters
must be separated using a comma (no spaces).
When a DSP-100 is inserted into a PCMCIA socket, the client driver will configure the
card as a series of COM ports, starting with the lowest available port number in the list.
IMPORTANT:
If the user specified resources are in-use by other devices in
the system, the DSP-100 will not be configured.
8.1.2.1 Example 1
DEVICE=C:\DSP-100\DSP100.SYS (3,100,5)
In example 1, the Client Driver will attempt to configure the DSP-100 as COM3 and
COM4 using I/O addresses 100-10F hex and IRQ 5. If COM3 or COM4 already exists,
or if the I/O address or IRQ resources are already in use, the DSP-100 will not be
configured. Furthermore, only one DSP-100 can be installed in this system.
